Hey, relatively new to the group, wanted to show off my build.

Using a Pi 3 with a 39" Insigna LED TV.


Frame is TIG welded and brushed aluminum, frame is 3/4" oak ply that was bondo(ed) and then painted. Whole thing is 24" tall and 36" wide.

The hotword detection is working and it’s passing it to the Google Assistant module and that module is working too

@bdream Sure so I had some 3/4" (19MM) oak plywood kicking around. I ripped it down on the table saw, I glued that up and put screws in the end and then covered them over with bondo

The screen runs to the edges, but not quite to the top.

I did some rough cutouts on the top for the speakers, and made a VESA mount plate out of sheet steel on the back

Speaker openings were pretty rough, but I planned on covering them.

Here are the 3D printed covers, I didn’t bother making the screws all pretty and hidden since there’s only about a foot between the top of the mirror and the ceiling

Here’s the whole thing painted, if you look in the corners you can see the 3D printed brackets that I’ve used to hold it to the wall.

@sdetweil I run a local makerspace, so I was able to talk to our metal shop guy and he had one, in total fairness I didn’t do the welds on the frame myself he did them for me, as this was my first attempt at TIG welding.

Awesome! That was it, thanks so much for the help.

Ok, here’s the bog standard config with just the hotword module loaded, still don’t get an icon for it.
I am noticing that in the terminal window there is a
[HOTWORD] No model to load

Even though there are models in the directory
/home/pi/MagicMirror/modules/MMM-Hotword/models
as well as
/home/pi/MagicMirror/modules/MMM-Hotword/snoboy/resources/models

Ah Ok, I guess I assumed the errors were bad.

So then I guess my next question is, why would Hotword detection not work? I’ve enabled it in the config.js and I get the Google Assistant icon at the bottom of my screen, but no hotword icon, and saying any of the built in hotwords doesn’t seem to do anything.

I’ve done test recordings from command line and the microphone is picking up audio, but just no dice on getting the mirror to respond to voice commands.

I’m trying to set up Google Assistant with hotword detection.
I’ve follow the tutorials on Github, but when I try to install snowboy I’m getting the output below.
I am running the latest Raspian build on a Pi 3. I’ve uninstalled and tried multiple times to install, I’ve even blown away the whole OS and Magic Mirror install and started from scratch.
